About this time, another circumstance sent a momentary panic through the stern hearts of the defenders of the fort. The ammunition was failing, and a large force, which had effected a landing, was in rapid march to storm the works. Moultrie instantly dispatched Marion to a sloop-of-war for a supply, and another message to Governor Rutledge at Charleston. Both were successful--both in season. Said the governor, in a note accompanying five hundred pounds of powder, "Do not make too free with your cannon--_cool, and do mischief_." With this fresh supply of ammunition, the fire, which had been relaxed, was redoubled. The British were astounded. They had congratulated themselves, upon the partial suspension of firing, that the fort was about to yield. But the new fury of the firing, on the part of the Americans, soon served to convince them of their error. They also redoubled their efforts, and, for a time, the contest was more terrible than ever. "Once," it is said, "the broadsides of four vessels exploded together, and when the balls struck the fort, it trembled in every timber and throughout its entire extent, and shook as if about to fall in pieces." The day was now wearing away, and still the contest was undecided. The British, reluctant to relinquish an object which in the morning they imagined so easily won, still continued the heavy cannonade; while the Americans, gathering strength and courage by what they had already accomplished, stood firm and undaunted. At length, the sun went down behind the distant shore, and darkness threw its ample folds on every object of nature. But now, through the darkness, flames shot forth and thunders rolled, presenting a scene of solemn and indescribable grandeur. The inhabitants of Charleston still lingered on their watchtowers, gazing out through the gloom towards the spot where the battle was still raging in its fiercest intensity. But they were not destined to hope and pray in vain. At about half-past nine, the fire from the English fleet suddenly ceased. They had fought long--fought with all the ardor and enthusiasm of friends to their king and his cause. But they had fought in vain. Victory decided for Moultrie and his patriot band, and it only remained for the English to withdraw, as well as they were able, their ships, which had been nearly disabled, and their crews, which had been dreadfully reduced.
